Hi, I am well aware of working in Sibelius, so please consider me for the job. I can send you a PDF file of the rearranged sheet music for choir version of Queen's song "Who wants to live forever", as a sample of my work. This wasn't all my doing, I have found the midi file of someone's choir version of this song, imported it into Sibelius and reworked it in some parts, but I think this is enough for you to see that I have enough knowledge to do a simple job such as this. Please contact me and I will send you the PDF as a sample of my work. Also, feel free to listen to my own music compositions in my portfolio if you like.
